Filter by:Although interim 18F-fluoro-2-deoxy-D-glucose-positron emission tomography (FDG-PET)/computerized tomography (CT) scan has emerged as a powerful prognostic tool in predicting treatment outcome in Hodgkin's lymphoma (HL) and diffuse large B cell lymphoma (DLBCL), the positive predictive value (PPV) of interim PET/CT scanning has not been determined in patients with peripheral T cell lymphoma (PTCL). The sequential interim PET/CT will be prospectively investigated to determine whether it provided additional prognostic information and could be a positive predictable value for the treatment of PTCL.
Background: - Researchers who are studying hairy cell leukemia, and how the disease compares with other disorders, are interested in obtaining additional samples from leukemia patients and healthy volunteers. The investigators are particularly interested in samples from individuals who have diseases that can be treated with a new type of drug called immunotoxin, in which an antibody carrying a toxin binds to a cancer cell and allows the toxin to kill the cell. Objectives: - To collect a variety of clinical samples, including blood, urine, lymph samples, and other tissues, in order to study the samples and develop new treatments for leukemia. Eligibility: - Individuals 18 years of age and older who have been diagnosed with leukemia or other kinds of blood and lymphatic system cancers, or who are healthy volunteers. Design: - Individuals who have leukemia will be asked to provide blood, bone marrow, urine, and tumor tissue samples as requested by the researchers. Healthy volunteers will provide only blood and urine samples. - No treatment will be given as part of this protocol.
The role of angiogenesis has been less clear in lymphoma than in solid tumors, in part related to the heterogeneity of disease and technical issues. In addition to vascular endothelial growth factor (VEGF) effects on angiogenesis and the integrity of tumor vasculature, autocrine VEGF-receptor (VEGF-R)-mediated signaling may play a role in lymphoma. Microvessel density, a measure of angiogenesis, is highest in peripheral T-cell lymphomas (PTCL), followed by diffuse large B-cell (DLBCL) and intra-follicular follicular lymphoma (FL).
The primary objective of this study is to evaluate the efficacy of Fludarabine, Adriamycin and Dexamethasone (FAD) as first line therapy in patients with Peripheral T-cell lymphomas (PTCL). 30 patients will be treated into this study.
Peripheral T cell lymphomas comprise 10-15% of all malignant lymphomas. The prognosis is significantly worse than that of aggressive B cell lymphomas. The prospects of elderly patients are especially poor, with an estimated disease free survival of only 25% after three years. Previous phase II trials have demonstrated a significant activity of the monoclonal anti CD52 antibody alemtuzumab in primary and relapsed T cell lymphoma. The investigators thus propose to investigate the value of adjuvant alemtuzumab in combination with dose dense CHOP-14 in patients with previously untreated peripheral T cell lymphoma.
RATIONALE: Monoclonal antibodies, such as alemtuzumab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from growing. Giving alemtuzumab together with combination chemotherapy may kill more cancer cells. PURPOSE: This phase I trial is studying the side effects and best dose of alemtuzumab when given together with combination chemotherapy and to see how well it works in treating patients with stage I , stage II , stage III, or stage IV peripheral T-cell lymphoma.
This is a tissue, urine, and blood banking protocol for cutaneous t-cell lymphoma (CTCL), eczema, and atopic dermatitis patients for current and future research.
